Rigol DG812 – 10 MHz Function/Arbitrary Waveform Generator

The Rigol DG812 is a dual-channel function and arbitrary waveform generator operating up to 10 MHz, engineered for design validation, education, and production test environments. It combines multiple signal generation modes—including function generation, arbitrary waveform synthesis, noise and pulse generation, harmonic synthesis, and analog/digital modulation—into a single instrument. The DG812 delivers 16-bit vertical resolution, 125 MSa/s sample rate, and SiFi II point-to-point sampling technology for low-distortion waveform reconstruction. A 4.3-inch TFT touchscreen provides intuitive control, while fanless operation ensures silent performance in lab and production settings.
